| Research Abstract |
In order to realize an ultraprecision machining technology of the future, we proposed an idea of the machining environment-controlled ultraprecision machining methodology and a design concept of the available ultraprecision machining system with diamond turning and ultraprecision grinding functions. And also, we carried out the detailed investigations on the proposed machining method and the development of a concrete machine system. As a result, the following conclusions can be obtained from a series of the research and development.
1. We could successfully developed an ultraprecision machining system for diamond turning and grinding with high performance to be effectively and rationally able to machine hard-to-cut materials.
2. We carried out rationally investigations on the machining method of titanium ally substrate, one of the hard-to-cut materials, and evaluated its proposed machining method. And we could ascertain applicability and availability of the proposed machining method.
3. We could clear the difference of tool wear and chipping condition, chip form and flow, surface roughness and profile of the machined surface when cutting the titanium ally substrate in the various machining environment. And based on the results, we proposed cutting mechanism of titanium ally in the ultraprecision cutting region, i.e., the depth of cut is nm orders.
